Ounces to Gallons (Customary Volume Conversion)

Units of volume in the customary measurement system are complex. There are eight ounces to one cup, two cups per pint, two pints per quart and four quarts per gallon. Converting between units that are far apart on this scale requires multiplying a large number of constants, for examples to get fluid ounces to gallons the conversion is (8x2x2x4) = 128 ounces per gallon. Because of the number of small units of measure, converting between customary volume units requires diligence. These worksheets deal with ounces to gallons, quarts to gallons, pints to gallons, gallons to ounces and many of the other variations of volume conversion.
